I woke up at 4:00 AM today, thanks to Gambit the World’s Smartest Dog. My son made the mistake of attempting a furtive trip to the bathroom, which set Gambit to growling. Like he’s never seen the lad before. I think he’s hard of seeing – the dog, that is.
It’s been five months since I completed my battery-powered insulin refrigerator, and I’ve discovered a design flaw that might require some rework soon.
When my daughter Ginger had her Type 1 diabetes onset last March, one of the first preps I put in place was getting a backup to our backup generator. Insulin is life, and the supply must be protected at all costs, and since insulin must be kept cold, refrigeration is crucial. I can’t allow any single points of failure in my insulin supply and delivery system, so we have multiple stashes of insulin in multiple fridges with multiple sources of […]
I had a dramatic and disappointing illustration of the law of diminishing returns this weekend. It’s wood-butchering time on the homestead – actually, it’s well past the time that I should have been putting up next year’s firewood, but the woodlot was snowed in until only comparatively recently. I’m sure there’s still a snow pile lurking around here somewhere.
I know the photo quality is a little poor, so don’t miss the negative sign and think we’re having a balmy morning for a change. Fifteen below zero at 7:30 on the morning of February 24, 2015.
My refrigerator battery backup project is finally complete and in service. I’ll wrap up the last phase of the build and talk about the next steps – no point just staying at version 1.0, after all.
We continue with what is quickly turning into one of my favorite builds ever. Today we’ll tackle the electrical design and build.
In part 1 of this series, I covered the design goals for a refrigerator battery backup for our small insulin fridge. In this post, the build continues with more casework, some cable management, and getting ready to install the electrics.
November 29, wake-up temperature: 9°. I’m no stranger to working outdoors in the cold, but it takes a while to acclimate, and it usually doesn’t get this cold and snowy until well into January. Time for some long-neglected indoor projects.
It all started so simply. Cold night, cold house, and my office is as far from the wood stove as anything can be and still be in the house. I needed to burn some dead dinosaurs to take the edge off the office before the sun came up and warmed it a bit. But even after the customary minute or two for the warm air to start, I was getting nothing but a cold breeze from the register. Hmmm… We […]
